Koisuru Futari no Mitsu na Yarikata

The one Mitsu likes is the class' #1 popular guy, Ryuuzaki,
but she always pretends to hate him.
BUT, more than anyone else, she wants to get near him...
All of a sudden Ryuuzaki KISSES Mitsu!
Is he serious? Or is he only teasing??
This bothering her, desperate Mitsu confesses to Ryuuzaki!?
